Coffee is a complex mixture of chemicals that provide significant amounts of chlorogenic acid and caffeine. In research findings published in mid 2004 in Diabetes Care, researchers at the Duke University Medical Centre in North Carolina found that caffeine interferes with blood sugar controlled, they found strong correlation between caffeine intake at mealtime and increased glucose and insulin levels among people with type 2 diabetes.
Many other studies have shown that excessive caffeine raises blood sugar. Caffeine inhibits glucose metabolism and thereby raise blood sugar levels which is dangerous for people with diabetes.
According to 2008 study published in Diabetes Care, the participant wearing a glucose monitor for seventy two hours revealed that when participants drank coffee (two cups of coffee daily), their blood sugar elevated by 8 percent.
Caffeine consumption also exaggerated the rise in their blood sugar after meals: by 9% after breakfast, 15% after lunch and 26% after dinner.
The findings are significant enough that the researchers recommend that people with diabetes consider reducing or eliminating caffeine from their diets.
